US President Donald Trump is doubling tariffs on Turkish steel and aluminium quoting ‘not good’ relationship with Turkey.

Washington and Ankara are at odds over the detention of US evangelical pastor Andrew Brunson on terrorism charges in Turkey. He is facing up to 35 years in prison if found guilty of supporting the unsuccessful coup to overthrow President Recep Tayyip Erdogan in 2016.

Trump decided in March to impose import duties of 25 percent on steel and 10 percent on aluminum imports from several countries including Turkey. He has drawn criticism from other nations for triggering the global trade war.
